Real Madrid manager Jose Mourinho says Kaka can leave the Spanish champions, but only for the right price.
The Brazilian has been linked with a return to AC Milan and was in sparkling form with two assists as Real thrashed his old club 5-1 in the latest friendly between the two clubs.

Real Madrid coach Jose Mourinho remained non-committal about where he will be next term after his side lost 2-1 in the Copa del Rey final against local rival Atletico Madrid to round off the "worst season" of his life.
